Description

本発明の実施形態は、補助接点の増設を容易にし得る真空遮断器の操作機構に関する。   Embodiments of the present invention relate to an operation mechanism of a vacuum circuit breaker that can facilitate the addition of auxiliary contacts.

従来、真空遮断器には、主回路となる真空バルブの接点と連動して動作する補助接点が設けられており、インターロックや外部への信号出力などに用いられている（例えば、特許文献１参照。）。   Conventionally, a vacuum circuit breaker has been provided with an auxiliary contact that operates in conjunction with a contact of a vacuum valve serving as a main circuit, and is used for an interlock or signal output to the outside (for example, Patent Document 1). reference.).

この種の真空遮断器は、図２に示すように、操作機構フレーム１の略中央部に真空バルブ２の可動軸に連結され、接点を開閉操作する主軸３が設けられている。主軸３には、図示右側にリンク４が連結されており、標準装備された標準補助接点５を動作させるようになっている。図示略中央には、真空バルブ２の入状態、切状態の表示をする表示部６を備えたリンク７が連結されている。   As shown in FIG. 2, this type of vacuum circuit breaker is provided with a main shaft 3 that is connected to a movable shaft of a vacuum valve 2 at a substantially central portion of an operation mechanism frame 1 and that opens and closes contacts. A link 4 is connected to the main shaft 3 on the right side of the figure, and a standard auxiliary contact 5 provided as a standard is operated. A link 7 having a display unit 6 for displaying the on / off state of the vacuum valve 2 is connected to the center of the figure.

また、補助接点を増設し、系統のシステム化に対応させるため、主軸３の図示左側にもリンク８ａ、８ｂを連結し、増設補助接点９を動作させるようになっている。これは、増設補助接点９を図示右方向に配置することが困難なためである。   In addition, links 8a and 8b are also connected to the left side of the main shaft 3 in the figure in order to increase the number of auxiliary contacts so that the system can be systematized, and the additional auxiliary contacts 9 are operated. This is because it is difficult to arrange the additional auxiliary contact 9 in the right direction in the figure.

これにより、主軸３が反時計方向に回動すると、リンク４が図示上方向に移動し、標準補助接点５を動作させる。同時に、リンク８ｂも図示上方向に移動し、増設補助接点９を動作させる。   As a result, when the main shaft 3 rotates counterclockwise, the link 4 moves upward in the figure, and the standard auxiliary contact 5 is operated. At the same time, the link 8b is also moved in the upward direction in the figure to operate the expansion auxiliary contact 9.

上記の従来の真空遮断器の操作機構においては、次のような問題がある。
増設補助接点９を設ける場合、リンク４のほかに、リンク８ａ、８ｂが必要となり、部品点数が増加し、組立作業が困難となる。また、リンク４と８ａ、８ｂの動作にずれが生じると、標準補助接点５と増設補助接点９の動作にもずれが生じ、系統のシステム化に影響を与えることがある。 The operation mechanism of the conventional vacuum circuit breaker has the following problems.
In the case where the additional auxiliary contact 9 is provided, the links 8a and 8b are required in addition to the link 4, and the number of parts increases, making assembly work difficult. In addition, if a deviation occurs in the operation of the links 4 and 8a, 8b, a deviation also occurs in the operations of the standard auxiliary contact 5 and the extension auxiliary contact 9, which may affect systemization of the system.

本発明の実施形態は上記問題を解決するためになされたもので、増設補助接点を設けるとき、部品点数の削減を図り、組立作業を容易にし得る真空遮断器の操作機構を提供することを目的とする。   An embodiment of the present invention has been made to solve the above-described problem, and it is an object of the present invention to provide a vacuum circuit breaker operating mechanism capable of reducing the number of parts and facilitating assembly work when an additional auxiliary contact is provided. And

上記目的を達成するために、実施形態の真空遮断器の操作機構は、真空バルブの可動軸に連結されるとともに、操作機構フレームに設けられた主軸と、前記主軸に固定された回動自在の第１のリンクと、前記第１のリンクに連結された移動自在の第２のリンクと、前記第２のリンク端に係止される駆動ピンと、前記駆動ピンの動作によって接点が開閉する標準補助接点および増設補助接点とを備え、前記標準補助接点と前記増設補助接点とを前記操作機構フレームの幅方向に一列配置するとともに、前記操作機構フレームの上部に設け、且つ、制御線を接続する端子を上方向に配置したことを特徴とする。 In order to achieve the above object, an operation mechanism of a vacuum circuit breaker according to an embodiment is connected to a movable shaft of a vacuum valve, and a main shaft provided on an operation mechanism frame, and a rotatable fixed to the main shaft. A first auxiliary link, a movable second link connected to the first link, a drive pin locked to the second link end, and a standard auxiliary for opening and closing the contact by the operation of the drive pin A contact and an expansion auxiliary contact, and the standard auxiliary contact and the expansion auxiliary contact are arranged in a row in the width direction of the operation mechanism frame, and provided at the upper part of the operation mechanism frame and connected to a control line Is arranged in the upward direction .

本発明の実施形態は、標準補助接点と増設補助接点とを同一のリンクで動作させることにある。以下、図面を参照して本発明の実施例を説明する。   The embodiment of the present invention is to operate the standard auxiliary contact and the additional auxiliary contact by the same link. Embodiments of the present invention will be described below with reference to the drawings.

本発明の実施例に係る真空遮断器の操作機構を図１を参照して説明する。図１は、本発明の実施例に係る真空遮断器の操作機構の構成を示す正面図である。なお、図１において、従来と同様の構成部分については、同一符号を付した。また、図は、操作機構の正面パネルを取外した主要部分を示すものである。   An operation mechanism of a vacuum circuit breaker according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a front view showing a configuration of an operation mechanism of a vacuum circuit breaker according to an embodiment of the present invention. In FIG. 1, the same components as those in the prior art are denoted by the same reference numerals. The figure shows the main part of the operating mechanism with the front panel removed.

図１に示すように、操作機構フレーム１の略中央部には、真空バルブ２の可動軸に連結され、真空バルブ２内の接点を開閉操作する主軸３が設けられている。主軸３には、図示左側に、板状の第１のリンク１０の一方端が回動自在に固定され、他方端にＬ字状の第２のリンク１１の一方端が可動ピン１２で連結されている。第２のリンク１１の他方端にはフック１３が固定され、中間部には真空バルブ２の入状態、切状態の表示をする表示部１４が設けられている。   As shown in FIG. 1, a main shaft 3 that is connected to a movable shaft of a vacuum valve 2 and that opens and closes a contact in the vacuum valve 2 is provided at a substantially central portion of the operation mechanism frame 1. One end of a plate-like first link 10 is rotatably fixed to the main shaft 3 on the left side in the figure, and one end of an L-shaped second link 11 is connected to the other end by a movable pin 12. ing. A hook 13 is fixed to the other end of the second link 11, and a display portion 14 for displaying the on / off state of the vacuum valve 2 is provided in the middle portion.

操作機構フレーム１の図示上部には、標準装備された標準補助接点１５と、系統のシステム化に対応させるための増設補助接点１６が構造的に一体化され、設けられている。標準補助接点１５の端部には、フック１３の移動により標準補助接点１５内の接点を動作させる第１の駆動ピン１７が設けられている。また、増設補助接点１６にも、第２の駆動ピン１８が設けられ、第１の駆動ピン１７と連結されている。なお、操作機構フレーム１の上部には、幅方向にスペースを取ることができるので、標準補助接点１５と増設補助接点１６を一列配置することを可能としている。   A standard auxiliary contact 15 provided as a standard and an additional auxiliary contact 16 corresponding to the systemization of the system are structurally integrated and provided at the upper portion of the operation mechanism frame 1 in the figure. At the end of the standard auxiliary contact 15, a first drive pin 17 that operates the contact in the standard auxiliary contact 15 by the movement of the hook 13 is provided. The extension auxiliary contact 16 is also provided with a second drive pin 18 and is connected to the first drive pin 17. Since a space can be provided in the width direction at the upper part of the operation mechanism frame 1, the standard auxiliary contact 15 and the additional auxiliary contact 16 can be arranged in a row.

ここで、標準補助接点１５と増設補助接点１６を構造的に一体化するとは、第１の駆動ピン１７と第２の駆動ピン１８を連結し固定して、両補助接点１５、１６を同時に動作させることを言う。   Here, the structural integration of the standard auxiliary contact 15 and the additional auxiliary contact 16 means that the first drive pin 17 and the second drive pin 18 are connected and fixed to operate both auxiliary contacts 15 and 16 simultaneously. Say to let you.

次に、動作を説明する。主軸３を反時計方向に回動させると、第１のリンク１０も反時計方向に回動し、第２のリンク１１が図示下方向に移動する。すると、フック１３が第１の駆動ピン１７に当たって係止され、第１の駆動ピン１７を押し下げ、標準補助接点１５を動作させる。同時に、第２の駆動ピン１８も押し下げられ、増設補助接点１６を動作させる。   Next, the operation will be described. When the main shaft 3 is rotated counterclockwise, the first link 10 is also rotated counterclockwise, and the second link 11 is moved downward in the figure. Then, the hook 13 hits the first drive pin 17 and is locked, and the first drive pin 17 is pushed down to operate the standard auxiliary contact 15. At the same time, the second drive pin 18 is pushed down to operate the additional auxiliary contact 16.

これにより、標準補助接点１５と増設補助接点１６を同一となる第１、第２のリンク１０、１１で同時に動作させることができる。また、表示部１４を第２のリンク１１の板面に設けているので、部品点数を大幅に削減することができる。更には、標準補助接点１５と増設補助接点１６を同時に動作させているので、組立作業や、フック１３の動作範囲を調整するなどの調整作業を容易とすることができる。   Thereby, the standard auxiliary contact 15 and the extension auxiliary contact 16 can be operated simultaneously by the same first and second links 10 and 11. In addition, since the display unit 14 is provided on the plate surface of the second link 11, the number of parts can be greatly reduced. Furthermore, since the standard auxiliary contact 15 and the extension auxiliary contact 16 are operated simultaneously, the assembling work and the adjusting work such as adjusting the operating range of the hook 13 can be facilitated.

なお、図示していないが、標準補助接点１５と増設補助接点１６へ制御線を接続する端子を上方向に配置すれば、制御線の接続作業を容易とすることができる。増設補助接点１６が不要な場合には、取外すことができる。   Although not shown, if the terminals for connecting the control lines to the standard auxiliary contact 15 and the additional auxiliary contact 16 are arranged in the upward direction, the connection work of the control lines can be facilitated. If the additional auxiliary contact 16 is not required, it can be removed.

上記実施例の真空遮断器の操作機構によれば、標準補助接点１５と増設補助接点１６を構造的に一体化し、第１、第２のリンク１０、１１で動作させるようにしているので、部品点数を削減することができ、組立作業、調整作業を容易とすることができる。   According to the operation mechanism of the vacuum circuit breaker of the above embodiment, the standard auxiliary contact 15 and the extension auxiliary contact 16 are structurally integrated and operated by the first and second links 10 and 11. The number of points can be reduced, and assembly work and adjustment work can be facilitated.
